[R] Numerical integration of a two dimensional function over a disk

2012-05-08 Thread yingfu xie
Hello, there!   Basically my problem is very clear. I would like to take a (numerical) integration of a function f(x,y) which can be quite complex of x and y, over a disk (x-a)^2+(y-b)^2<= r^2 (with r constant). However, after some search in R, I just cannot find a function in R that suits my pu
